Pumps

I am based in Thailand and therefore availability of pump types may affect this: I am building a fish pond next to the house and am thinking of using a nearby small stream to recycle the water 24/7 to remove 'waste' rather than put in a filtration system; the water in the stream is PH7. The stream is about 25 metres away and the head from stream to waterfall discharge point about 5 metres. My understanding is that an external pump pushing the water would be best with the overflow return by gravity. Research on the net suggests that a 'solar' pump would be a costly option, taking years to recover the cost, and might struggle to do the job 24/7 anyway. Any suggestions on pump type and capacity would be appreciated, balancing initial outlay with running costs and longevity at 24/7.
Sorry – forgot to say that the capacity of the pond is about 2300 US gallons.

Need to know the size of the pond: OK 2300 gallons
Need the amount of water you wish to remove from the pond to achieve the desired cleaness: EX: How many fish, how clean
Need to know what the capacity of the small stream is to provide water. EX: 1 foot wide stream 1 foot deep or 10 foot wide stream 5 feet deep
